What needs to be done to unexpire this? I have exactly the same problem.
Like the OP I have confirmed that aplay plays fine to the iec958 device
but pulseaudio seems to alias it's iec958 oputput to analog. I also
have a colleague with the same card so this bug affects at least 3 of
us. My card is the Xonar U7 Echelon Edition which I believe is exactly
the same card as the OP, just different packaging and curiously a
different alsa-name: Xonar U7 Echelon Ed.
I don't really understand alsa/pulseaudio config etc but happy to
product/hack config files etc. to test any ideas.
Since aplay to hw:3,1 worked for me I wondered if Raymond's comment
about iec958 needing to be first device was the problem and simply
tried editing my USB-Audio.conf to be :
# If a device does not use the first PCM device for digital data, the device
# number for the iec958 device can be changed here.
USB-Audio.pcm.iec958_device {
# "NoiseBlaster 3000" 42
"Xonar U7 Echelon Ed." 1
This made no difference (but then I did say I don't understand
alsa/pulseaudio so was probably stupid)

Title:
Asus Xonar U7 S/PDIF output not recognized by pulseaudio
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
The external USB audio card Asus Xonar U7 is capable of both analog and
digital output.
ALSA name for the digital (S/PDIF) output is hw:1,1, and it is listed in
aplay -l output, and aplay can output to it:
aplay -D plughw:1,1 sample.wav. So, direct alsa sound works fine.
However, pulseadio does not recognize the digital output of Xonar U7,
it offers only analog output.
